Enum ProcessState 

pub enum ProcessState {
    Running,
    Exited(i32),
    Signaled(i32),
    Unknown,
}

Process state tracking.

Variants

Running

Process is running.

Exited(i32)

Process has exited with the given status.

Signaled(i32)

Process was killed by a signal.

Unknown

Process state is unknown (e.g., after kill attempt).

Implementations

impl ProcessState

pub const fn is_alive(self) -> bool

Returns true if the process is still running.

pub const fn exit_code(self) -> Option<i32>

Returns the exit code if the process has exited normally.

Trait Implementations

impl Clone for ProcessState

fn clone(&self) -> ProcessState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProcessState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ProcessState

fn eq(&self, other: &ProcessState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
